Amazon India Inventory Sync Checklist

  • GST certificate โ€” active + name matches
  • Trademark under All 45 TM classes supported โ€” REGISTERED
  • PAN + COI / LLP / Partnership deed
  • Cancelled cheque + 3-month bank statement
  • Brand deck (5-10 slides)
  • Photography spec (1000ร—1000 white BG)
  • Instagram handle at threshold
  • Category certifications (BIS/FSSAI/CDSCO as applicable)
  • Brand authorization letter (if OEM)
  • MRP labelling proof
  • D2C site URL
  • GA4 + pixel setup for cross-channel attribution

Common Mistakes to Avoid

  • Filing before trademark is fully REGISTERED (not "applied")
  • Using D2C photography instead of Amazon India's marketplace spec
  • Skipping the category-buyer intro in first 30 days
  • Launching PLA before 2+ reviews land on hero SKUs
  • Ignoring pricing parity ยฑ3% across Amazon India + other channels
  • Not reconciling settlements weekly (2-8% GMV silent leak)

Expert Opinion

โ€œAmazon India rewards brands that treat it as a curated media channel โ€” not a passive sales channel. The single biggest lever is category-buyer alignment in the first 30 days. Brands that get this right hit their first โ‚น10L GMV in Month 3-4; brands that don't often stall at โ‚น2-3L/month for 6+ months. If inventory sync is your current bottleneck, the fix is almost always dossier quality + agency-filed submission for 2โ€“15 days (Brand Registry) turnaround.โ€
